Researchers Mimic Extracting Energy From Black Holes in the Lab
As black holes spin, they drag space-time along with them, and scientists have proposed that this could be a source of energy for an advanced civilization, harvesting momentum from material ejected from this twisting spacetime. The concept has been generalized, and it's theoretically possible to extract energy from anything spinning. Now, researchers have mimicked the process in the lab, beaming electromagnetic waves at a spinning object and extracting energy.
